Information: INFORMATION:

In order to test PCMCIA com ports successfully without getting the write fault error from MS-DOS Prompt you must type the following lines :

C:\>mode com2:9600,n,8,1,p ( wait for a response )

C:\>echo atz > com2 ( you should receive a new c:\> )

If you do not get to a new prompt or the system hangs, there is a possible modem problem.

Below is a batch file for your convenience with the above lines. To run the batch file you type the following:

c:\>COMTEST COMx ( COMx, x Meaning Port Number, example: COM2, COM1, COM3 ).

Batch File:

MODE %1:9600,n,8,1,p
